Not sure what you mean by swing arm mount? This is just the holder, but it will fit to any of our mounts. So if you have the dash mount and arm yes it will fit.

Will this fit the iPad Air? It looks like the side of the mount where it holds the iPad will interfere with the home button.the button on the iPad Air is a lot closer to the edge of the iPad then the one in the picture. I would need to access the button a lot. Thank you.

Yes you can easily press the home button with this holder. This holder is pretty common for the iPad Air.
